The current on-line User's Guide (HTML version), at the end of
Section 3.3 (Compiling a unit), contains the paragraph:
The compiler produces lowercase files, so your unit will be found,
even if your source file has uppercase letters in it. Only when
the compiler tries to recompile the unit, it will not find your
source because of the uppercase letters.
I don't believe this is any longer the case. But I don't know
for what version of the compiler this stopped to be a necessity.
At some version, the compiler started preserving the casing of
the source file in the generated *.ppu and *.o files.
It would be good to state explicitly in the User's Guide to what versions
of the compiler the paragraph applies, and to add an explanation of what
the situation is with newer versions.
It wouldn't hurt to point in Section 3.3 to the compiler option -Ur.
